I m really not sure if I m pregnant or not. The last couple of nights I have been feeling sort of nauseated I haven t vomited or anything just feel weird. Could this possibly be a sign of early pregnancy?? I don t want to get my hope up or anything but I want to know. I also want to add I have previously been on the depo shot the last one was in January of this year. The entire time I have been on the shot I have had no period. I am just wondering cause when I was having periods I never felt nauseated.
